Patent JP-S5920204-B2 (JP)
IPC: H04J3/04
Filed: 1979-11-02
Abstract: An adaptive delta modulation system is disclosed which features an improved digital compandor which may be used with a digital integrating network. The compandor executes a companding algorithm having a nonlinear characteristic to provide a rapid increase in step size to follow the fast rising start or fast decaying end of talkspurts in input signals so as to minimize any slope overload distortions and to provide a small increase or decrease in step size during the smooth portion of the talkspurts in input signals to reduce any granular noise effect. The step size generated by the compandor is directly related to the input signal level, providing a maximum companding range in which good signal-to-noise characteristics are preserved for the soft or low voiced speaker as well as for the loud voiced speaker and providing a fast transient response most suitable for telephone applications. The step size logic of the compandor has a built-in minimum step size circuit which insures that a well behaved idle pattern of alternating ones and zeros will appear at the digital output when the input signal is zero, and which provides a mechanism to rapidly build up the step size when an input signal appears. The step sizes can be integrated with an integrating network to reconstruct the input signal. The compandor may be used in conjunction with a digital integrating network which exhibits, for example, a system function, having either a single pole or a zero and a pair of poles which may be real or complex. The filter constants can be chosen to match any input spectrum to obtain optimum performance. A significantly high signal-to-noise ratio and a wide companding range have been obtained with the disclosed compandor. By providing storage elements in the compandor and in a digital integrating network and storing the calculated intermediate values, a plurality of input for output analog signals can be time division multiplexed and delta modulated with a single delta modulation system.

Abstract: A test pattern generator that generates test patterns used for testing semiconductor ICs. So far, test patterns are stored in an SRAM and are sucessively read out therefrom. Generally, an SRAM has a memory device integration density which is smaller than that of a DRAM. When a DRAM having a large memory element density is used instead of an SRAM, it is necessary to refresh the stored content of the DRAM at a constant period. Consequently, it is impossible to read test patterns during the refreshing, and test patterns are not continuously generated. According to this invention, a DRAM is used as a test pattern memory (32). A control circuit (21) generates address generation clock pulses (ACK), a read control signal (RC), a refresh control signal (REF) and write clock pulses (WCK). In response to the address generation clock pulses (ACK), an address generating circuit (31) generates addresses for reading the DRAM (32). In response to one of the address and read control signal (RC), a test pattern is read out from the DRAM (32) and is written onto a FiFo memory (22) in synchronism with the write clock pulses (WCK). The test patterns are continuously read out from the FiFo memory (22) in synchronism with the pattern generation clock pulses (PCK). The average reading speed at which the test patterns are read out from the DRAM (32) inclusive of the refresh time is determined to be greater than the reading speed from the FiFo memory (22). When filled with test patterns, the FiFo memory outputs a full flag (FF). In response to the full flag (FF), the control circuit (21) no more generates the address generation clock pulses (ACK), read control signal (RC) and write clock pulses (WCK). These signals are generated again when the full flag is cancelled. Thus, the test patterns are continuously read out from the FiFo memory (22) even when the DRAM (32) is refreshed at a constant period.

Abstract: An improved port liner and its method of assembly into a cylinder head of an engine such that an air insulating layer is formed between the outer periphery of the liner and the inner diameter of an exhaust passage. The liner is a thin, stainless steel member having an arcuately-shaped section and a straight section which permits it to be inserted only one way into an exhaust passage. This is important for it allows for automated machine assembly of a valve guide which must be pressed through an opening located in the outer surface of the liner. The method of assembly also limits the physical contact between the liner and the cylinder head and this in conjunction with the air layer reduces the loss of thermal energy from the passing exhaust gases.

Abstract: PURPOSE:To simply form a bump and also connect bumps with each other at a low temperature by a method wherein one of the bumps is a bump mainly containing tin while the other mainly contains gold or silver. CONSTITUTION:A gold bump 18 is formed on an LED array 4, while a tin bump 20 is formed on a glass substrate 2. The formation is done by supplying gold or tin wires from a capillary and pressing the LED array 4 or the glass substrate 2 while they are heated. This heat and friction heat due to ultrasonic oscillation at this time and pressure cause the metal wire or tin wire to be bonded to the LED array 4 or the glass substrate 2 to be a ball. If the metal wire or the tin wire is cut above the ball immediately after the bonding, the bump 18 or 20 can be obtained. Since gold or silver and tin form an eutectic compound at approximately 20 deg.C, bumps can be easily interconnected by means of thermocompression bonding, ultrasonic bonding or the like.

Abstract: PURPOSE: To reduce a processing load, to reduce deviation between a video and an audio and to prevent increase in memory capacity by speech speed conversion-processing an input audio signal with a speech speed conversion- processing means. CONSTITUTION: Since a ring memory 7 becomes easy to become an overflow just before state the more in a program whose vocalizing speed is faster, a compression rate is decided so that an audio reproducing speed becomes close to a double speed. On the contrary, the compression rate is decided so that the audio reproducing speed becomes close to a one time speed the more in the program whose vocalizing speed is later. Thus, the audio reproducing speed becomes the speed of the double speed or below and according to the original vocalizing speed, and a natural reproducing audio is obtained.

CONSTITUTION:A specimen 1 is fixed to a table 2, and a direct current is impressed on an exciting coil 9, and impact wave generating AC signal voltage (Vs) is impressed on a movable coil 10, respectively. Then, a bobbin 11 or the table 2 in its turn operates along a prescribed target waveform according to the voltage Vs, and applies an impact wave running along the target waveform to the specimen 1. Afterwards, signal supply to the coil 10 is stopped, and at the same time, this is short-circuited through a switch 10a. However, the table 2 collides with a shock absorbing mechanism 20 stil at the maximum speed, and the mechanism 20 absorbs kinetic energy of the table 20 by a coil spring 22, and pushes back the table 2 by the elastic force.
